Wolo Manufacturing Horns

About Wolo Manufacturing Corporation

Since 1965, Wolo Manufacturing Corporation has been a trusted supplier of marine and automotive solutions for lighting, horns, alarms, and more — keeping drivers safe whether they're at the job site, on the water, or in their daily driver. A second-generation, family-owned company, Wolo's mission has always been to develop innovative products that meet the most stringent standards for quality and reliability.

Founded as a one-person operation with a commitment to manufacture a single patented hood lock, Wolo has grown into a second-generation family-owned and operated business — while holding firm to that original mission of delivering the very best quality products and customer service.

Horn Design & Technology

Wolo Manufacturing Corp. is the leader in horn technology — spanning electric, air, truck, marine, electronic specialty, air, and back-up alarms — offering the highest quality and largest selection for cars, trucks, and industrial equipment. Their horn lineup is remarkably diverse: Wolo horn lines include OE replacement horns, industrial horns, musical and novelty horns, as well as air horns for truck, heavy-duty, and marine applications.

For drivers who want the thunderous sound of a train horn without the bulk, Wolo's air horn kits deliver. Wolo air horns are recognized and valued for their compact size, incomparable quality, reasonable price, and ease of installation. These complete kits typically include trumpets, mounting hardware, hose, and relay — everything needed for a straightforward installation.

On-Board Air Systems

Behind every great air horn is a reliable compressor. Wolo's air horn compressors and on-board air compressor systems are engineered to power their horn lineup with precision. Wolo air horn compressors have been specially designed for use with Wolo 2- or 3-trumpet air horns and low-pressure truck horns, and feature a compact size that fits great in small engine compartments. Wolo also makes various compressor and tank systems, including the Model 858 TORNADO — a heavy-duty compressor specially engineered for applications that need large volumes of high-pressure air, perfect for powering air-locking differentials, train air horns, and light-duty pneumatic tools.

Emergency & Warning Lights

Beyond acoustics, Wolo is equally respected for its visual safety solutions. Wolo Manufacturing Corp. provides safety lighting for commercial, industrial, municipal, and agricultural applications — including lightbars, warning lights, safety lights, work lights, grille lights, warning beacons, and strobe and LED safety lights. Their LED light bars are a popular choice for emergency responders, utility fleets, and off-road enthusiasts alike. The patented lighting optics are designed in-house to ensure proper light distribution and compliance to specifications, and Wolo lighting is designed and tested to meet the strict SAE J845 standard that measures light output in 360 degrees.

Wide Application Coverage

Wolo safety products and accessories are built to fit a variety of specific application needs, including automotive, commercial, industrial, and agricultural. Wolo's primary specialization lies in the production of horns, with a diverse range that caters to all types of vehicles, including cars, trucks, boats, motorcycles, and industrial equipment. Whether you're a daily commuter wanting a more commanding presence on the road or a fleet manager outfitting work vehicles with proper audible and visual warning systems, Wolo has a solution engineered to perform.
